I am also 5'10 and I have lost 20 lbs since May 17th. I stopped counting carbs after I found out it don't lose any more if I eat less carbs or more. I lose about 2 lbs a month with my tom and thats the way it is.Actually I think I lost more since I upped my carbs a little. But I know you have that vacation coming up and want to lose faster, I am no help there. At my weight of 173 I still would have to wear shorts over my 2 piece bathing suit or wear a one piece in front of people.
